Today is February 29, 2016.   February 29???   February only has 28 days, right?   Not always.   Most years that can be evenly divided by 4 are Leap Years.   Also presidential election years in the United States.  How much time does the earth requires to orbit the sun?   It is exactly 365 days, 5 hours, 48 minutes and 46 seconds.    So, to keep the seasons and months together, an extra day is added every 4 years.   Almost.   On century years, the ones that end with 00, there is a leap year only if the year can be evenly divided by 400.   This can get confusing.   But all that means that today, February 29 is a special day.   Some stores will even have special Leap Year sales.   And, if you were born on February 29, you only have  your real birthday once every 4 years.   So, Pizza Hut says that if that is you and you can prove your birthday is February 29, you will receive a free one topping personal pan pizza today.   Also, tradition says that ladies may propose marriage to a man today, on Leap Day.   So, whatever you do today, make it special.   This is a special day, and you will not see February 29 again for 4 more years.
